Industrial lubricants are widely used, there are many types of base oil, such as: pure mineral oil, PAO poly ɑ rare hydrocarbon synthetic oil, polyether synthetic oil, alkylbenzene oil, biodegradable lipid oil. When they become a kind of industrial lubricants, they can not be mixed with each other, such as polyether synthetic oil and other industrial oil mixed, its performance will be significantly reduced. Industrial lubricants in different applications, the additives are not the same. Outdoor use of hydraulic oil to have suitable for local temperature changes, we can not use indoor sealed environment of hydraulic oil. In addition, as the use of heavy-duty gear oil and molding oil is also different conditions, heavy-duty gear oil contains extreme pressure additives to ensure that can be used in harsh environments, molding oil, usually pure mineral oil, without additives.
